Describe and correct the error in solving the equation. Can someone help me with these three problems (17,18,19)

Problems Solved Correctly:

17) Find Common Denominator

Combine Fractions With Common Denominator

Multiply All Terms By The Same Value To Eliminate Fraction Denominators

8 · 4 = 8

Cancel Multiplied Terms That Are In The Denominator

8 x 4 = 8 (y+8/8)

8 x 4= y+ 8

Multiply The Numbers

8 x 4 = y + 8

32 = y +8

Subtract 8 From Both Sides Of The Equation

32 = y + 8

32 - 8= y +8-8

Simplify

Subtract the numbers

Subtract the numbrs

Move the variable to the left

y = 24

18) Subtract 7 From Both Sides Of The Equation

28y+7=21

28y+7-7=21-7

Simplify

Subtract the numbers

Subtract the numbers

28y=14

Divide both sides of the equation by the same term

28y=14

28y/28=14/28

Simplify

y=1/2

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
